I should have my 09 GT 500 by the first of next week. I want a programer, cold air intake, and exhaust. I would like suggestions on which manufactures I should choose. Please tell me of any negative feedback on the following products. I think the FRPP axle back exaust. FRPP cold air intake, and the SCT X3 programer. I read an artical in the summer issuse of "Mustang Performance" where they do step by step build up of a stock 07 GT 500. Seems like this is the way to go. I don't want to hurt the car, just a little more. Is a dyno tune a must when you add these parts? Any suggestions would help before i spend money on the wrong things. Do you reccomend getting hooked up with a local Mustang performance shop with a dyno? I am in the Memphis, TN area. Thanks
